casing 16, said sleeve being provided with ports 36 and 37 adaptedto'register with the portsl 33 and 34, and being provided with otherportsl40A -and 41 adapted to register with the ports 24 and 25.' Thebottom ofthe sleeve is provided with a spider 42, said spider beinprovided with a tongue or rod 43, said ro extending downV and along the30. This tongue is upwardly and downwardly notched at 44 and 45,saidnotches 4providing dog-engaging shoulders for the dogs 46 and 47which are downwardly and upwardly pivoted at 49 and :50, said dogsheingheld if'the notches and urged toward ciprocating piston 56, said pistonbeing suitably ported and cored at 57 and 58, 4the cores terminating inports -59 and 60 which are adapted to successively register With theports- 1 vof the draw-off connection.

This piston is also provided with ports 61 and 62 adapted to registerwith the ports 36 and 33, and 37 and 34 respectively, of the sleeve andcasing. Suitable cores 63 are provided in the piston to provide acommunication between theports 24 and 40 through the piston and throughthe ports-61, 36 and 33 to the conduit 15. The

piston is si-milarlycored at 65 to establish' communication betwcentheports 25 and 41 ,through the piston and through ports- 62, 37 and34 tothe conduit 14. f

The piston is provided with a piston rod 65 which may be suitablythreaded in the shoulder or boss 77, said piston rod beingprovided atits lower end with a member 6,6 suitably notched at 67 and 68, saidmember -being provided with .a spring engaging shoulder 78. Upwardly anddownwardly sloping cams 69 and 70 are provided on opposite sides of themember 66 at the bottom and'top thereof respectively, said cams beingadapted to cooperate with the pins 52 and 53 respectively, to operatetheir respectiveivoted'at 72 to the parti ion 51, said dogs eingvprovided with rollers or other antifriction means 73 adapted tocooperate with the notches provided in the member 66, said dogs beingurged intosaid notches and toward each other by meansy of a spring 74pro- `videdtherebetween.,v Disposed around the piston rod 65 and betweenthe shoulders 78 ofthe member 66 and the spider 42, there is a spring75,- and similarly disposed betweenthe spider 42 and the boss 77 of thepiston 56, therea'is a spring 76. H

In the operation ofthe dispensing apparatus, assuming that the parts ofthe deto 7 inclusive, when the motor 20 is started, fluid will be pumpedthrough the conduit 18, through thejpump 19, through the conduit 21 andinto the manifold 23. The parts of the `device being in the positionshown in Figure 3 the ports 24 and 40 will be in registry; therefore,the fluid will flow through said ports, through-the core provided in thepiston 56, through the ports 61 and 36 f the piston and sleeverespectively, and through'V the port33 into the conduit 15 communicat-`paWlS. Upwardly extendging dogs 71 are4 -vice are in the positiont shownin Figures 3 ing with the measuring chamberl 11. As-

suming then that thel measuring chamber 10 has already been filled,fluid Afrom said measuring chamber will discharge through the conduit14, through the ports 34 and 37, and through the passage 57 of thepiston, and through the ports 59 and 17 to the'discharge hoseconnections.I

, When the cylinder 11 has been filled, fluid is prevented from passingthrough the air 'connections 13 by any suitable valve means providedwithin the chamber 11,'and a back pressure will accordingly be built upin the casing 16 of the control unit. This back'pressure will actlon theb'ottoin of the piston 56 and when sufficient pressure hasibeen builtup, will cause the piston 56 to move upwardly, moving the port 61 out'of registry with the port 36 and the discharge passage 57 out ofregistry'with the ports 37 and 34. The piston 56 'in moving upwardlymoves the piston rod.65 with it, causing the spring 75 to be compressedbetween the shoulder 73 of the member 66 and the spiderf42. Cam 69 willcome in contact with the piny 52 and will operate thereon to move thedog 46 out of enga-gement with the shoulder 44 of the rod 43, andthecompresison of the springwill cause the sleeveto move positively upward,moving the port 40 out of registry with-'the port 24, cutting offcommunication ofthe ports 24 and 28 and causing the ports'41 and 25 tocome into register. In this position.,

,the ldog 47 will act tolock the sleeve in upward-position by engagementwith shoulder 45. v

It will then be understood that fluid will be pumped through the conduit21, through be built up in thel top ot' the manifold 23, through portsand 41, through core 64 in the piston, through the ports 62, 37 and 34,and through the conduit l1 to the measuring cliambei 10. The fluidalready measured in the measuring chamber 11 will pass through theconduit, l5, through ports 33 and 36, through the core 58 and the port6l) aml out through the discharge port. 1T to the discharge mechanism,and it will readily be understood that any excess fluid trapped in thebottom of the casing lf duc fo the pressure necessary to move. the partsof the valve. will pass through the port 22T. which has been uncoveredby the upward movement of the sleeve. into the discharge manifold 26 andthrough the conduit 22 to the source of supply.

l lt will'readily be appreciated that when the mesauring chamber 10 hasbeen filled, a reverse movement sin'iilar to that just de scribed 'willbe effected; that is, pressure will the casing 16, moving the pistondownwardly, cutting off communication between the core 58 and the ports3G and 33,and bringing the core 57 into registry with the ports EST and34. spring 76 'will be compressed between the spider 42 and the boss 77,and the lam 7() will contact the pin 53 of the dog 47 which has been inengagement with the shoulder 15, moving said dog out of engagement withsaid shoulder and allowing the spring 76 to move lthe sleeve downwardlyinto that'position shown in Figure 3 and as already described. In thisposition, dog 46 will lock the sleeve. in lowered position by engagementwith shoulder 44, in which position the port 28 will be uncoveredallowing any excess accumulation of' Huid to ldrain back to the sourcethrough the conduit Dogs 'i'l are pro# vided-to engage. in the notches(f7 and 68 in order to hold the piston in the correct positions ofoperation so that there will always be a positive registry of the portsand the parts of the unit will not move until and unless the correctpressure has been built, thereby insuring that the correct charging andcorrect supply and discharging of the measuring chambers is effected.
